BALL-BEARING.

SPECIFICATION forming part of-Letters Patent No. 660,324, dated October23, 1900.

Application filed October 6 1899. Serial No. 732,787. (No model.)

To all whom it may concern:

Be it known "that I, SOHUYLEE WAYNE BULL, a citizen of the UnitedStates, residing at Rochester, in the county of Monroe, in the State ofNew York, have invented certain new and useful Improvements inBall-Bearings, of which the following is aspecification,

reference being had to the accompanying drawings.

My invention relates to an improvement in ball-bearings whereby the coneis provided with an adjustable washer which excludes dust or foreignsubstances, while permitting the cone to be adjusted or refitted asoften as may be required.

My improvements are fully described and illustrated in the followingspecification and the accompanying drawings, the novel fea tures thereofbeing specified in the claims annexed to the said specification.

In the accompanying drawings, Figure 1 is a partial longitudinal sectionof a ball-bearing embodying my invention applied to the rear Wheel of abicycle. Fig. 2 is a section of the cone and washer detached. Fig. 3 isan end elevation of the cone and washer as seen from the inside. Fig. 4is an end elevation. Figs. 5 and 6 represent a modified form of thecone.

A represents the wheel-hub; B, the cup inserted in the end of the hub;G, the cone; D, the balls, and E the washer, which is made adjustablelengthwise on the cone.

F is the shaft on which the cone is threaded, as indicated at G, and His a nut which clamps the side frame I I against the outer end of thecone, a washer J being interposed, if desired.

The washer E consists of a sheet-metal disk,

provided on its inner surface with a ring K,.

E has a perforation of corresponding shape adapted to fit the cone, aflange L being formed on the washer around the opening extending inward,so as to give the washer a firm support on the cone. The washer fits thecone snugly and with sufficient friction to insure its remaining inplace in any position lengthwise of the cone to which it may beadjusted. Thus in case it becomes necessary to adjust the cone inwardfor any rea- 6o sonwear,refittin g, or otherwise-the washer having beenpressed thereon, with its inner 'surface in contact with the cup, itwill retain such position until another adjustment of the cone isrequired, and if it is desired to renew the supply of lubricant to theballs this is readily accomplished by sliding the washer outward. If myimprovement be constructed of certain proportions, the balls will be allthe time in contact with the felt, or an inner ring K,of felt or othersuitable material, may be employed. The edge of the washer E may beturned over the edge of the felt ring K, as indicated at N. It will beobserved that my improvement is applicable to a large proportion of theball-bearings now in use for bicycles, motor-carriages, &c.

O is the ordinary perforated flange for the attachment of the spokes.When my improvement is applied to the rear hub of a chain-bicycle, thehub is provided with the sprocket-wheel P.

In Figs. 5 and 6 I have represented a modi-' fied form of the cone 0, inwhich it is provided with a longitudinal slot Q, a form to which in suchcase the opening in the washer is made to correspond.

My invention is simple and cheap in its application. It is very durable,since it does not employ any springs, and it may be apo plied to anycone-adj usting hub now in use.

I claim 1. The combination in a ball-bearing, of the adjustable conehaving a flattened side,

and a longitudinally-adjustable Washer hav- 5 ing a flange fitting thecontour of said cone and secured thereto through frictional contacttherewith.

2. In a ball-bearing, a cone flattened-on two sides,and alongitudinally-adjustable washer 10o having a perforation fitting thecontour of the cone and secured thereto through frictional contact.

3. In a ball-bearing, a cup having antifric- 5 tion-balls, a coneadapted to coact with said balls, a longitudinally-adj ustable Washerfrictionally secured to the cone, and a facing of absorptive materialfor said washer, said fao ing bearing against a fixed part of theballbearing and against the antifriotion-balls.
